Abstract: Currently, the wavelet technique has a weakness for detecting damage at the edge of two-dimensional signals. This weakness arises from the nature of the wavelet transform procedure, which shifts the signal by differencing the signal’s pair arrays in the neighborhood. This study introduces the mode shape projection method as an efficient technique for damage detection of two-dimensional signals in rectangular laminated composite plates to eliminate the weakness of damage detection by the wavelet method. In other words, this paper proposes creating two one-dimensional waves containing information about damages or faults in signals from vibration amplitude signals of composite plates to have an efficient damage detection method. Results show that the proposed method acts much better than wavelet transform and detects damages in numerical and experimental investigations with high performance for various damage scenarios.
